Question

3 true or false 2 points species having genetic diversity is a good thing. true false 4 multiple choice 2 points why is biodiversity important for ecosystems and the planet? it attracts tourists to natural areas. it helps maintain ecological balance, provides food, and supports various ecosystem services. it only matters for scientists, not the general population. it makes ecosystems look more colorful. 5 fill in the blank 2 points the biosphere gets its energy from the type your answer... 6 multiple choice 2 points what are some examples of terrestrial and aquatic ecosystems? terrestrial ecosystems include oceans and lakes, while aquatic ecosystems include forests and grasslands. terrestrial ecosystems include forests, grasslands, and deserts, while aquatic ecosystems include oceans, rivers, and lakes. terrestrial ecosystems include mountains and valleys, while aquatic ecosystems include forests and grasslands. terrestrial ecosystems include fish and coral reefs, while aquatic ecosystems include mountains and valleys.

Explanation:

• Question 3: Genetic diversity allows species to adapt to changing environments, resist diseases, and evolve. So having it is beneficial.
• Question 4: Biodiversity is crucial as it maintains ecological balance (e.g., through predator - prey relationships), provides food sources (like crops, livestock), and offers ecosystem services (such as pollination, water purification).
• Question 5: The sun is the primary source of energy for the biosphere. Through photosynthesis, plants convert solar energy into chemical energy, which then moves through food chains.
• Question 6: Terrestrial ecosystems are land - based (forests, grasslands, deserts), while aquatic ecosystems are water - based (oceans, rivers, lakes).

Answer:

• Question 3: True
• Question 4: It helps maintain ecological balance, provides food, and supports various ecosystem services.
• Question 5: Sun
• Question 6: Terrestrial ecosystems include forests, grasslands, and deserts, while aquatic ecosystems include oceans, rivers, and lakes.
